| De-Initializes the RTC registers to their default reset values. | |
| ErrorStatus | LL_RTC_Init (RTC_TypeDef *RTCx, LL_RTC_InitTypeDef *RTC_InitStruct) |
| Initializes the RTC registers according to the specified parameters in RTC_InitStruct. | |
| void | LL_RTC_StructInit (LL_RTC_InitTypeDef *RTC_InitStruct) |
| Set each LL_RTC_InitTypeDef field to default value. | |
| ErrorStatus | LL_RTC_TIME_Init (RTC_TypeDef *RTCx, uint32_t RTC_Format, LL_RTC_TimeTypeDef *RTC_TimeStruct) |
| Set the RTC current time. | |
| void | LL_RTC_TIME_StructInit (LL_RTC_TimeTypeDef *RTC_TimeStruct) |
| Set each LL_RTC_TimeTypeDef field to default value (Time = 00h:00min:00sec). | |
| ErrorStatus | LL_RTC_DATE_Init (RTC_TypeDef *RTCx, uint32_t RTC_Format, LL_RTC_DateTypeDef *RTC_DateStruct) |
| Set the RTC current date. | |
